The goal is to ensure that the Binder code works not to end to end test a specific phone. If you have shown it to work properly in an emulator and on an actual phone, it's reasonable to assume that the overall implementation is sound and can be merged to the mainline. It's not like kernel updates were pushed directly to phones. Manufacturers will now be able to do their own test on their specific model to ensure it works fine.
